Add social buttons to top of each page.
Make links bold by default. Fixed breadcrumbs line-height.
Display captions in lightbox when possible.
Fixed social buttons positioning on desktop layout.
Tweaked desktop horizontal menu behavior -- inactive top-level menus are only dimmed after the active menu is expaned, rather than as soon as it is hovered.
Gave #menu a background color on mobile layout, so collapsed menu appears to span whole height of viewport.
Added "Full Title" column option for pfi_posts_table block.
Link only post title in pfi_posts_list blocks.
